IMPROVEMENT IN COTTON-CLEANER.

'TQ .ALL WHOM IT MAY CONCERN;

Be it vknown that I, JOSEPH W. THOBN, ofthe city of Courtland, county ofLawrence,'in the State of Alabama, have invented a newandusefulImprovement inCotton-Cleaners; and I hereby declare that the followinglis a full, clear, and-exact description of my invention, referencebeing' had to the accompanying drawings making a part of thisspecification, in whichi Figure I, platei 1, is a side elevation ofv mycotton-cleaning machine.

Figure I, plate 2, a plan view of the machine.

Figure 2,'plate 2, a longitudinalsectional elevation of the machine.

VSimilar letters of reference apply to similar parts of the machine. v

The object of my improvement is tc pro-vide a machine for cleaningcotton, with a revolving feeding-drum, of a simple construction andoperation, by the `application of whichmachines for cotton-cleaning maybe cheaply and easilyfe'd. r'

Y Toenable others skilled in the art to make and use my invention, Iwill proceed tondescribe its construe tion and operation. y I Y j F Fis'the wooden or metallic framework oi'the machine; B B, the fans orcylindrical beaters,.made in the usualA way a lengthy, description ofwhich I do not deem necessary to give, as my invention does not bearprincipally on them. M Mis the cleaning-bo x, with the usual wirearrangement around it. F A is the drnm'of my feeding-apparatus, itshollow cylinder mounted on-an axle, B, anddivided -insideby partitions,six, or less or more, in number, Aresting' on the axle, and withintheex'terior envelope E E.' Said feeding-drumorcylinder, thus prepared,is set on the machine `on the uprights V P, and. protected, outside, byexterior envelope E E, and should4 be placed'so as toiill up the topopening space O P of x'zleaning-boxv M. On one end of shaft A B is set acircular ratchet, C R, and lever-catch C T. Catch C T is set firmly onlever L, which hangs on axle A B, as a fulcrum, for the purposehereinafter shown. The opening between vthe lower part of cleaning-box Mand :envelope E-Eofthe drum is-shut up or o'pe'n at will, by door D.Said door is held in properrplace by and fast* cned tight to axle X,whichin its rotarynlternate movement, as heieinafter shown, opens and'closes doorD. On one end of'axle X, on 'the same side of the machinewith ratchet'C R, is set a small lever, L', which'is held in properposition .by catch C VK, and which will,'when catch C K is removed, fallin positionl? S, shown in red lines inthe drawings, iig. 2, plate 2. iThis movement of lever L isvmade sure by the alternate falling andrising ofa rod and Weight, W, set for the purpose, at the opposite endofpshaft X.

The machine is set `in motion by means oi' pulleys P L and PLL', andgearing ab coller-Belt on pulley a b-drives wheel a, which, by. meansofpinio'n p, drives wheel 6,' which, by means of pinion p', drives cog-vwheel L -Onthe inside faceof said wheeld arey projected circular lugs lgZ. f/"Z" 9; l y' being nearer` the centre of` the. wheel fthanthe twoothers. In the rotary movement cf `whee1 d, lug Z" g",ypassing abovecatch-lever L", 4knocks against catch C thuis Vallowing lever L', /withweight W to fall to the position P S, shown'jn red, plate 1, drivingopen rdoor D. Next comes lug Wg, which, passing under catch-lever L',catches lever L', and pushes it up, .aswell as weight W, until catch C Khasbeen thus lpermitted `to holdL' in its former position, and door D isclosed again. Mean-ivhile lug lg travels up, pushes lever- L up, saidmovement acting on ratchet C K, so asl to drive druinF A, asshown perarrowin red ink, and when it (lever L) escapes lug 1g, lever Lfalls ofits own weight into its former position, catch C T thus catching on'thenext notch or tooth of the ratchet.` The relative positions' oflng'lgl'g Z" y" are so calculated that, through the medium of thepartslacting in connection therewith, drum F'A will throw a new supplyof'cotton to thecleaningplace M only when afsupply of clean cotton hasbeen ejected through door D, and said door closed up again by thedescribed movement otlug l' g', on lever L. v 4

I have not thought necessary to describe'` any of the parts of themachine WhichI do not intend to `claim as new. Nor do I intend to claimbroadly, in this-specicactiomthe whole of the machine herein described,

s'laid machine having beenmainlydescribed and claimed in my patent,dated sixteenth day of'October, eighteen hundred and sixty.

I have simplified considerably the first machine I invented -oncottonfcleaning, by rendering' the feedingA i apparatus self-acting,.andconsiderably simplifyingA the gearing. My above-described invention andimprovement give allI the fnciiity and chenpness as'weil as perfectionof work that can' be desired in a contrivance of that kind. Onesingiebelt, connected.v ivith any power, steam or otherwise, sets thewhole in motion, and the cotton thrown in the machine in itsdirty,'crnde-statefcomes out neat and clean. Having thus described myinvention7 what I claim, and dsire to secure by Letters Patent of theUnited States, is i Y Y I 1 Feeding-drum F A, catch-1ever L, C T,ratchet C R, and lug lg, the Whole combined and constructed andoperating in the manner and for the purpose above 4set forth anddescribed. v

-2- Lever L', catch C K, door D, and weight W, the whole combined in themanner and for the-purpose above set forth and described. I I I 3. Thecombination of drum F A, its catch-lever L C T, and ratchet C R, anddoor D, lever L', and catch C K, and weight W, with a cotton-beating andcleaning-machine, the whole constructed land operated inthe manner andfor the purpose nbove'set forth and described.
